1. Vascular Surgeons
Vascular surgeons play a critical role in the management of superior mesenteric artery (SMA) syndrome. This condition arises from compression of the duodenum, the first part of the small intestine, between the SMA and the aorta. This compression, often due to diminished mesenteric fat, restricts the passage of food, leading to symptoms such as postprandial abdominal pain, nausea, and vomiting. The anatomical expertise of vascular surgeons is essential for accurately diagnosing and surgically correcting this vascular arrangement. For instance, a patient presenting with chronic postprandial pain and weight loss might undergo a CT angiogram revealing a narrowed aortomesenteric angle and duodenal compression. A vascular surgeon would then be consulted to consider surgical options to relieve this compression. Surgical approaches might include duodenojejunostomy, a procedure that bypasses the compressed section of the duodenum, or, less commonly, SMA transposition, which involves moving the SMA to a new position to alleviate the compression.
The involvement of vascular surgeons extends beyond simply performing the necessary procedures. Their understanding of vascular anatomy and physiology contributes significantly to the diagnostic process. They collaborate with gastroenterologists and radiologists to interpret imaging studies and determine the optimal course of treatment. This collaboration ensures a comprehensive approach, addressing both the immediate symptoms and the underlying vascular issue. For example, a vascular surgeon might work with a radiologist to analyze the degree of duodenal compression and assess the feasibility of endovascular stenting versus open surgery. Their combined expertise leads to informed decisions, maximizing the potential for successful outcomes. Furthermore, the involvement of vascular surgeons can reduce potential complications, such as arterial injury or thrombosis, which could arise during procedures involving the SMA.
In summary, the specialized knowledge and technical skillset of vascular surgeons are integral to effective SMA syndrome management.

The primary goal of surgery is to relieve the compression on the duodenum, restoring normal passage of food and preventing further complications. The choice of surgical procedure depends on the specific anatomical characteristics of the compression, the patient’s overall health, and surgeon expertise.
-
Duodenojejunostomy
This procedure involves creating a bypass around the obstructed segment of the duodenum by connecting it directly to the jejunum, the second part of the small intestine. This bypass allows food to bypass the compressed area, relieving the obstruction and restoring normal digestive flow. Duodenojejunostomy is often the preferred surgical approach due to its relatively lower risk and effective relief of symptoms. For instance, a patient with chronic postprandial pain and weight loss unresponsive to conservative treatment may undergo a duodenojejunostomy to alleviate the obstruction and improve nutritional intake. This procedure effectively bypasses the compressed area, allowing for unimpeded passage of food through the digestive tract.
-
Strong’s Procedure (Duodenal Division)
Strong’s procedure involves dividing the duodenum just proximal to the area of compression and reattaching it to the jejunum further downstream, bypassing the compressed segment. This is another effective bypass procedure, although slightly more complex than duodenojejunostomy. It is often considered when duodenal mobilization is difficult due to adhesions or other anatomical complexities. In cases of recurrent SMA syndrome following previous surgeries, Strong’s procedure can provide a more durable solution.
